(我知道这是一个重复的问题,但楼主问的原因是错误的。我不是在暗示我问的原因是正确的,但让我们看看。)
我们有一个在非标准端口号上运行的web服务。尽管用户似乎能够记住端口号,但有时他们会错误地键入http:而不是https:。有人问我们是否可以在该端口上提供HTTP服务,然后将它们重定向到同一端口上的HTTPS。听起来很邪恶。。。我喜欢它的可用性,但感觉也许这应该是浏览器的工作?
我看到的一个解决方案是“在Jetty前面编写自己的代理”这个解决方案会起作用,但我不认为它会起作用,因为我不相信我能编写一个与Jetty本身一样高效的代理。此外,即使代理本身是有效的,所有数据仍然需要进行额外的跳跃,这保证了无论如何都会减慢流量。
还有比这更好的方法吗?也许Jetty本身有一些地方可以嵌入协议检测逻辑,这将允许利用它们的速度,同时还可以消除代理引入的额外跃点。
基于答案“是的,我们可以”,我构建了适用于当前码头9.3.11的代码,我想有些人会感兴趣。

更新:自jetty-9.4.15起。码头内置v20190215对港口统一的支持;请参见此答案。
这是可能的,我们已经做到了。此处的代码适用于Jetty 8;我没有使用Jetty 9进行测试,但这个答案与Jetty 9的代码类似。
顺便说一句,这被称为端口统一,显然Glassfish使用Grizzly长期以来一直支持它。
基本思想是生成一个org的实现。日食码头。服务器连接器,可以查看客户端请求的第一个字节。幸运的是,HTTP和HTTPS都让客户端启动了通信。对于HTTPS(通常是TLS/SSL),第一个字节将是0x16(TLS)或
在这里的代码中,我们利用了Jetty的SslSelectChannelConnector本身扩展了SelectChannelConnector,并有一个newPlainConnection()方法(调用其超类来生成非SSL连接)和一个newConnection()方法(生成SSL连接)。因此,我们的新连接器可以扩展SslSelectChannelConnector,并在观察客户端的第一个字节后委托给其中一个方法。
不幸的是,我们需要在第一个字节可用之前创建AsyncConnection的实例。该实例的某些方法甚至可以在第一个字节可用之前调用。因此,我们创建了一个LazyConnection实现了AsyncConnection,它可以在以后确定它将委托给哪种连接,甚至在它知道之前将合理的默认响应返回给某些方法。
基于NIO,我们的Connector
将与SocketChannel
一起使用。幸运的是,我们可以扩展SocketChannel
以创建ReadAhead SocketChannelWrapper
,它委托给“真正的”SocketChannel
,但可以检查和存储客户端消息的第一个字节。
一个非常粗糙的部分。我们的连接器必须覆盖的方法之一是自定义(endpoint、请求)。如果我们最终得到一个基于SSL的endpoint,那么我们可以直接传递到我们的超类;否则,超类将抛出ClassCastException,但只有在传递到其超类并在请求上设置scheme之后。因此,我们传递给超类,但在看到异常时撤消设置方案。
我们还重写了isConfidential()和isIntegral(),以确保servlet可以正确使用HttpServletRequest。isSecure()以确定是否使用了HTTP或HTTPS。
尝试从客户端读取第一个字节可能会抛出一个IOException,但我们可能必须在不需要IOException的地方进行尝试,在这种情况下,我们会保留异常并稍后抛出。
扩展SocketChannel在Java中看起来不同

更新:有关如何将单个端口重定向到HTTPS和HTTP侦听器的说明,请参阅此答案。如果出于任何原因,您不使用该解决方案,请参见以下内容:
<罢工> 不可能在同一个端口上同时从超文本传输协议和https传输流量。Jetty使用两个完全不同的连接器来绑定到安全和不安全的端口。事实上,我遇到的每台Web服务器都将这两个协议绑定到两个完全不同的端口。
出于可用性考虑,我建议使用默认端口,这会对用户完全隐藏端口。默认情况下,http使用端口80,默认情况下,https使用端口443。因此,如果您将连接器配置为分别在端口80和端口443上运行,那么您的用户不必键入端口,您的开发团队也不必处理在HTML、CSS、JavaScript和其他资源的绝对路径中包含端口号的问题。
Jetty被设计成一个独立的Web服务器,与较早版本的Tomcat不同,Apache建议Tomcat在Apache HTTP服务器之后运行。因此,只要您没有其他HTTP服务器在运行,并且使用这些端口,您就应该能够将Jetty配置为在默认端口上运行,而不会出现任何问题。这来自经验。我们正是以这种方式经营码头的。
最后,一个协议可以绑定到多个端口。因此,如果您当前在端口8080上运行Jetty用于超文本传输协议,在端口8443上运行Jetty用于https,您可以保持这些连接器处于活动状态,并为端口80和端口443添加另外两个连接器。这为您的应用程序中仍在使用端口号的部分启用了向后兼容性,并为您提供了前进的时间。
